A spring .33 bears against the upper side of the block 30 and at itsupper end bears against the frame of the machine. Another spring 34:bears at its upper end against the block 30 and at its lower end againstthe frame of the-machine, so that the block is interposed between. twosprings 33 and-'34.

I claim 1. A tape attaching and severing machine having, in combination,mechanism for attaching a strip of adhesive tape to a piece of sheetmaterial, mechanism to intermittently feed said sheet material with atape attached thereto, a tape guide, a rocker arm, a cutter fast theretoand positioned above the tape, a rocker frame, a second cutter fast tosaid rocker frame and positioned beneath the tape and connected to saidrocker arm, said rocker arm and rocker frame being relatively sopivotally mounted that downward movement of the upper cutter will causethe lower cutter to be moved beneath the tape and the tape to be severedby said cutters.

2. A tape attaching and severing machine having, in combination,mechanism for attaching a strip of adhesive tape to a piece of sheetmaterial, mechanism to intermittently feed said sheet material with atape attached thereto, a tape guide, a rocker arm, a cutter fast theretoand positioned above the tape, a rocker frame, a second cutter fast tosaid rocker frame and positioned beneath the tape and connected to saidrocker arm, said rocker arm and rocker frame being relatively sopivotally mounted that downward movement of the upper cutter will causethe lower cutter to be moved beneath the tape and the tape to be severedby said cutters, said tape guide being mounted on a second rocker armpivotally mounted to swing in a plane transversely of the cutting edgesof said cutters, and means on said first-named rocker arm adapted toengage the second rocker arm and cause it to be moved toward and awayfrom said upper feeding mechanism whereby the tape may be severed, thesevered, end caused to assume an advance position relatively to the tapeguide and the severed end fed by the tape guide to the sheet materialfeeding mechanism.

In testimony whereof I have hereunto set my hand.
